Well, I don't know how investment expenditure is treated in Canada, but in most countries it's in the operating budget unless it's a very major project. In other words, filling in potholes in a highway is something that is regarded as an operating expenditure, typically, rather than a capital expenditure.
But I want to briefly note the following. There are multiple options for the relationship between capital and operating expenditure. What we've discussed are the extreme cases: two separate budgets on the one hand, or an integrated consolidated budget on the other hand.
Between these two extremes there are many ways of presenting, displaying, and voting on capital and operating expenditure. You don't have to completely lose sight of capital investment in order to consolidate them in a budget.
